Cirrus spissatus are the highest cloud formations in the troposphere where all the weather occurs in the low and middle latitudes. These clouds can form out of cumulonimbus clouds or aggregation of cirrus clouds in the sky. In this photo, from the weather sounding shot, it is very clear that the clouds have formed at an altitude of well above 8km making them very high clouds and from the visible satellite image it is also very clear that the photographed clouds are actually a mess of cirrus clouds which were much visible in the daytime satellite imagery. Such photographed clouds normally harbinger the approach of bad weather through their mares` tails. In fact, at the very same time, a mid-latitude cyclone was entering the Mediterranean from the Rhone Valley as evidenced by the surface pressure chart of the fourth thumbnail when compared with the third thumbnail of the visible satellite image. The freezing level indicated the ascent of a milder airmass which is a very typical signature of an approaching mid-latitude cyclone or low pressure system. Confirming known theory and weather folklore, bad weather did occur over the Maltese Islands particularly at night of the following days. The first thumbnail shows a wider view or a beautiful panorama of high clouds slowly becoming cirrus spissatus.
